ruby - Library class methods aren't loaded by rails -

i have library defines base class other classes derive from. rails, on initialization, should provide of classes library. rails, however, doesn't recognize class methods inherited library class. here example:

model: app/models/mailing_address.rb:

require 'account_model' class mailingaddress < accountmodel   # class accessors, initializer , method end 

library class: lib/account_model.rb

################################### # accountmodel #  # super class inherited  # domain classes of application. # responsible api calls ,  # error handling. ## class accountmodel   class << self     def get_all id = nil      # class method implementation     end     ##     # id     # fetch method, parses url provided child class in path hash     # , performs appropriate fetch     # method returns class instance set fetch     def id       # class method implementation     end      def update_existing options       # class method implementation     end      def create_new options       #class method implementation     end      def delete_existing id       # class method implementation     end    end 

these methods wrap api calls using httparty gem. on load, methods get , get_all recognized. however, create_new, , update_existing not:

app/controllers/mailing_address_controller.rb:

def update     @mailing_address = mailingaddress.update_existing params[:mailing_address]    . . . end 

throws following error:

processing mailingaddressescontroller#update json . . . completed 500 internal server error in 133ms  nomethoderror (undefined method `update_existing' mailingaddress:class):   app/controllers/mailing_addresses_controller.rb:17:in `update 

in passenger, need reload tmp/restart.txt, in webrick, need restart server.

i not see behavior in irb.

here i've tried far no success:

• adding initializer file in config/initializers
• adding require statements (as in example) in each model class
• wrapping library class in module
• renaming troubling methods (update_existing => update, foo, etc)

i have never seen behavior in rails app before, have library class works fine.

i'm running: - ruby-2.1.1 - rails 4.03 - passenger 5.07

update:

while attempting investigate further, uncovered yet issue:

i added class method mailingaddress:

class mailingaddress < accountmodel . . . def self.debug_methods   return self.methods end 

which throws "methodnotfound" exception. since does work in rails console, not in webrick or passenger, i'm tempted there server caching going on.

update

after shutting down , restarting, situation reversed:

-webrick processes request -passenger processess request successfull -rails console throws error:

webrick , passenger:

processing mailingaddressescontroller#update json . . . completed 200 ok 

console:

mailingaddress.update_existing params nomethoderror: undefined method `update_existing' mailingaddress:class 

i'm guessing it's first come first serve whomever gets loaded class.

config.autoload_paths set correctly:

config.autoload_paths += %w(#{config.root}/lib) 

last update workaround seems work clobbering tmp/ directory , restarting (passenger need have touch tmp/restart.txt ran).

this, however, crappy workaround. bug!

you have call method on instance of class:

mailingaddress.new.update_existing params[:mailing_address] 

or

@mailing_address.update_existing params[:mailing_address] 

if don't need update_existing instance method can move outside of self block.

also, might consider putting account_model.rb file in app/models. way won't have require @ top of mailing_address.rb
